It is sometimes said that the day of reckoning is always one more day away, and in the case of the water sector and the potentially seismic ramifications of what comes next for Thames Water and the business water sector, this day was set to be at some point in the summer before being delayed again.
With the end of the runway looming again, and Thames Water set to run out of money before the end of 2026, The Guardian reports that regulator Ofwat have offered to stop fining the failing, struggling water company in exchange for “undertakings” to fix the problems they would have been fined for.
This, alongside a previous payment plan that allowed Thames Water to defer the biggest penalties ever issued by the water regulator, has sparked intense criticism and action to try to stop it.
It has led to legislation being introduced in Parliament, according to the BBC, which would stop water companies from delaying or deferring fines, although exactly how this would function in practice remains to be seen.
However, it does ask some important questions. Why are water companies allowed to delay paying fines when a business customer would be shut off or prosecuted? Could Thames stop paying the fine entirely? And is any of this preferable to letting the company fall into administration?
Why Are Water Companies Allowed To Delay Paying Fines?
The authority that has the authority to levy financial penalties also sets the terms for repayment, and when Thames Water was fined £122.7m for persistent breaches related to raw sewage and mismanagement of dividend payments, the company was supposed to pay in full by 20th August 2025.
However, water companies can request a payment plan and submit a proposal to pay the total over time. Ofwat do not need to accept it, but can do so at its discretion if they believe it is in the best interest of customers to do so.
To that end, Ofwat allowed Thames Water to pay just 20 per cent of the fine at the end of September 2025, and then delayed the payment of the remaining sum to one of three dates:
- If the company restructures in such a way that the business has enough liquidity to pay, Thames has to pay within 30 days.
- If the company falls into a Special Administration Regime (SAR), it must pay the fine 30 days after exiting it.
- No matter what, Thames must pay by the end of the 2029/2030 financial year, which concludes at midnight on 31st March 2030.
No matter what happens with any currently pending agreements regarding future fines, this penalty must be paid in full.
It must also be noted that this only applies to Ofwat fines. Other government departments, such as the Environment Agency, can impose their own fines and penalty payment structures.
Should Water Companies Be Allowed To Delay Paying Penalties?
The problem Ofwat has is that it has a responsibility not only to customers but to businesses and the privatised water industry. This means that its primary tool for ensuring compliance also potentially harms the sector as a whole.
Any additional fines to a company such as Thames Water would bring them closer to insolvency and bankruptcy, which would immediately trigger a Special Administration Regime and bring the company, at least on paper, into government ownership.
Partly because of this, Ofwat has historically treated water companies relatively softly, which is part of the reason why raw sewage was pouring into areas of historic natural beauty and why Ofwat itself is being abolished.
The problem is that decisions made to avoid SARs and ensure water companies benefit often come at the expense of business and residential customers, who have to deal with poor water quality, higher bills and significantly worse service without the option to get water from elsewhere.
Deferring fines and setting up “undertakings” systems that allow fines to be avoided entirely are seen as rewarding failure and allowing a company to fail to comply with its statutory duties, both elements that are anathema to customers and the general public.
What Is The Alternative To Delayed Fines For Water Companies?
The real reason why these capitulations are being suggested is to avoid hearing the case for nationalisation, using figures that have since been debunked to claim that it is too expensive to do so in order to push a market-led solution.
This desire to avoid an alternative is the main source of leverage for the creditors who are currently in control of Thames Water. Their threat is that Ofwat give them five years of leniency from fines, or the company is nationalised via statute.
